Hello ,
I am unable to install obs-studio on centos 7. Please find the install error output os-release uname -a
I have installed most of the updates and dependencies still installation is throwing errors ... any idea how to fix this ?

This is the same version from nux release
should I ask in obsproject community ?

Same? I don't know, the version you have installed is x264-libs-0.148-23.20170521gitaaa9aa8.el7.x86_64 and nux-dextop has x264-libs-0.142-11.20141221git6a301b6.el7.nux.x86_64. Does not look the same to me.

Besides, the key point here is not the version of the package but the libraries those packages provide. obs-studio-libs from nux-dextop requires libx264.so.142 and the version of x264-libs you have installed provides libx264.so.148. 142 != 148.
